Abstract
Subject to an inclinedl oad, w e obtaint he energyr eleaser ate for a crackw ith an interfaceb oundedb y two different isotropic elastic materials. The energy release rate is calculated by the path independent E-integral using the finite element method with a singular element. In the finite element analysis, we impose avoiding the contact of the extended crack which happens in the large angle kinking. Under the maximume nergyr eleaser ate criterionw, e examineth e extensionb ehavioro f interfacec rack.
